Interstate Business Route 40

Eastbound Interstate 40 approaches Exit 285, Junction Business Loop I-40/Hopi Drive east, U.S. 180 southeast to St. Johns, and Arizona 77 south to Snowflake and Show Low. Photo taken 07/13/08.

Interstate 40 has 31 actively signed business loops, including the Winston-Salem business loop freeway. In addition, it has one decommissioned business loop and a few other potential future business loops that are currently signed as business U.S. routes.

Listed in the 1991 California State Signing Log, this business route follows Old U.S. 66-95 (National Trails Highway) from west to east via River Road, North Street, Broadway, Acoma Street, and Front Street. The route remains signed as of March 2013. This business route also provides a connection to the north section of Arizona 95 en route to Bullhead City, which is not connected with the southern portion of the route.
See California @ AARoads - Business Loop Interstate 40 - Needles for the route guide.
This business route used to follow Historic U.S. 66 between Exits 48 and 53 via Andy Devine Drive through the city of Kingman. On May 30, 2003, Business Loop I-40 through Kingman was decommissioned with approval by AASHTO in order to transfer maintenance of the highway from the state of Arizona to the city of Kingman. The route is now signed solely with Historic U.S. 66 shields, with occasional business loop shields. Generally, Arizona DOT does not permit non-state maintained routes to serve as officially signed business loops.

Business Loop I-40 in Seligman follows Historic U.S. 66 between Exits 121 and 123.
Ash Fork
This is Historic U.S. 66 and Old U.S. 89 between Exits 144 and 146. Notice how it's "old" U.S. 89 and "historic" U.S. 66.
Historic U.S. Route 66 between Exits 163 and 165.
Multiplex heaven! Historic Route U.S. 66, Business Loop I-40, U.S. 180, Old U.S. 89, Arizona 89A, and Interstate 17 signs are everywhere along the main street called Route 66. I've been here, and I still can't tell you exactly where the southern end to U.S. 89 is located, but I can tell you which roads will take you to Interstate 40 and Interstate 17. Business Loop I-40 leaves Interstate 40 at Exit 191 and returns at Exit 201.

Winslow (Loop)
"I was standing on a corner in Winslow, Arizona, such a fine sight to see..." The Eagles (and Jackson Browne) probably sung (and wrote) about a corner that was Historic U.S. 66 and is now Business Loop I-40. This business connection is between Exits 252 and 255. The western end of Business Loop I-40 connects to Business Spur I-40 (see next entry).
Winslow (Spur)
Winslow also has a Business Spur I-40 that is mostly unsigned. According to Alan Hamilton, the Business Spur I-40 in Winslow is actually marked, but only at the end away from the interstate. It doesn't connect to anything in particular. The railroad bridge was not part of old U.S. 66. It was built in 1975, about the same time the mainline Interstate 40 was built. Old U.S. 66 followed the same route as Interstate 40; it didn't cross the railroad here. The Business Spur designation does make it the state's repsonsibility, rather than Navajo County. It goes west from Interstate 40, Exit 252. East of Exit 252 is the conventional business loop (see entry above).

This business route serves Gallup between Interstate 40 Exits 16 and 26, with the exits signed "Business Loop I-40, West and East Gallup." Gallup is another city along Historic U.S. 66 and is the southern terminus to U.S. 491 (formerly designated as U.S. 666 until AASHTO approved its renumbering on May 30, 2003).
This business route follows Historic U.S. 66 through the city of Grants between Exits 81 and 85.
Back in the 1970s-1980s, when U.S. 66 was still designated through Albuquerque, Central Avenue was also signed as Business Loop I-40. Once U.S. 66 was decommissioned in 1985, the residual route was left as Business Loop I-40. However, the business route is not signed from either direction on mainline Interstate 40. However, as of July 2008, the business loop signage was found along Central Avenue paired with U.S. 66 in a green guide sign. Several instances of this kind of signage is still present in and around downtown Alburquerque.

Business Spur I-40A connects Interstate 40 to Historic U.S. 66 at Exit 0, which is very close to the Texas-New Mexico State Line. The Exit Authority lists this business spur in its 2000 guide. There is a local route from the west end of the spur (at the state line) that returns traffic to Interstate 40 on the New Mexico side.

The business route follows Amarillo Boulevard, and the eastern half is cosigned with U.S. 60. The entire routing follows Historic U.S. 66.

This Business Loop Freeway was approved by AASHTO on October 2, 1992, and remains signed to this day. It is partially cosigned with U.S. 158, U.S. 421, and North Carolina 150; mainline Interstate 40 is now routed to the south. This section of Interstate 40 was removed from the Interstate Highway System due to its substandard construction; however, some projects have improved the freeway including a.
Business Loop I-40 in Greensboro was a brief designation for the original Interstate 40 freeway through Greensboro. The business loop, which was designated in February 2008, was an attempt to reroute Interstate 40 traffic around the downtown area. However, Business Loop I-40 was eliminated in September 2008 due to motorist confusion. Former Business Loop I-40 included a brief overlap with Business Loop I-85 (former Interstate 85 freeway) near downtown Greensboro. During the short time period when the business route was in use, both Interstate 40 and Interstate 85 were rerouted onto the Greensboro Bypass, which bypasses downtown to the south. This section of Interstate 40-85 was removed from the Interstate Highway System due to its substandard construction, including the infamous "Death Valley" segment. The Death Valley segment has been reconstructed and now meets Interstate standards again. The west end of the former business loop freeway almost connected with the Winston-Salem Business Loop I-40 freeway. The first part of the Greensboro Bypass, which carries Interstate 85 around the southeastern quadrant of the city, opened in January 2004. The Interstate 40 section of the bypass opened on February 21, 2008; the business route was signed on the old freeway alignment at the same time until its elimination in September 2008.
The northern half of Interstate 440, the Raleigh beltway, was known as Business Loop I-40 until June 9, 1991. On that date, AASHTO approved the elimination of Business Loop I-40 in favor of newly formed Interstate 440. It's not clear to me what drove NCDOT to designate a beltway as a business loop - perhaps the only part of that name that was fitting was "loop." The beltway mostly avoided the downtown area, which is where most business loops go.

The only Interstate 40 business route in California is in Needles near the Colorado River. Business Loop I-40 follows Historic U.S. 66 (San Bernardino County Route 66) via Broadway Street, which makes several turns along its path including this turn at its intersection with River Road. Continue ahead for River Road north to Arizona 95 (not signed here, oddly) or turn right for Business Loop I-40, Historic U.S. 66, and San Bernardino County Route 66 east to downtown Needles. U.S. 95 is surprisingly signed here for the path to its southbound continuation. Business Loop I-40 reconnects with U.S. 95 at the other end of the loop, at Exit 144. Photo taken 03/24/13.
